BRICK JOINTER AND BAKER.

Application filed June 12,

To '(IZZ 'urlaom it may concern;-

Be it ltnown tl at l, CHRISTIAN Crims- TENSEN, citizen of the United States, re siding at lilinneapolis, in the county of Henncpin and State of: lilinnesota, have invented a new and useful Brick Jointer and Baker, ot which the following is a specification.

My invention relates to improvements in 'nting and raking tools for brick layers.

Its object is to provide a simple, durable, and inexpensive, composite tool of this hind, which may be readily and effectively handled and quickly and easily converted to its ditlerent uses.

Wit 1 the foregoing and other objects in view, which will appear in the following description, the invention resides in the novel combination and arran ement of parts and in the details of construction hereinat'ter described and claimed.

in the drawings, Figs. 1 and 2 are perspective views illustrating reversed relations of the tool and showing the same as used in smoothing or finishing joints oi ditierent widths; l is also a perspective of the tool illustrating the same as used in r l a joint between courses of briclz; Fig. i a central longitudinal sectional view, in detail, taken through the end of he tool to which the raher blades are applied, and Fig. 5 is a perspective view of a blade having a tooth -l'or raking corners.

Referring to the drawings, it will be observed that my improved tool includes two tubular men'ibers and 11. Material cut out of said members leave elongated slots 12 and 13 therein and permit of easily shrinking and tapering the end portions, as indicated at 10" and 11 in the principal figures of the drawings. Instead of discarding the portions out out of the member 10, I do with the parts out out of the men'iber 11, I employ said portions as arms i l for joining the members 10 and 11 in. spaced parallel relation. The tips of said arms 14 are inserted in slots 15, "formed in the member 11, and sprung outward under pressure, as shown in Fig. 4, to secure said arms l-l to said member 11. The membore 10 and 11 serve alternately as handles and joint smoothing or finishing elements. In other words, the member 10 (Fig. 1) serves as a handle. When the member 11 is used in dressing a joint between bricks and said member 11 (Fig. 2) serves as a handle, then the member 10 is used as a 1923. Serial No. $44,358.

jointer. The member 10 is greater in diameter than the member 11, which variance in diameters suits the tool for use in linishing oints both wide and narrow.

l adaptmy improved tool not only for smoothing the cement joints between bricks, but for raking out the cementing material as is often done in rough-finish work. A plurality of blades 16 having raking teeth 16 are supplied, the teeth being of differ ent dimensions to suit joints of different widths, and to provide ior'the raking out of more or less material as maybe desired. These blades are severally applicable to the tool, each blade having a slot 17 therein to receive the shank of a set screw 18. This set screw (Fig. l) is threaded in a plug 19 brazed or otherwise secured in one end of the member 10. The head 18 of said screw bears against the outer face of a blade 16 (Fig. 3 and binds said blade against the inclined bearing surface A formed by the end of the member 10 and the outer face ot' the plug 19. The pitch of a blade 16 clamped against said inclined bearing surface A, causes the raker teeth 16 to readily "iollow a joint, thereby enhancing the ease of operation of the tool. The slots 1'? in the blades 16 permit 01 ready attachment of said blades to and detachment thereof from the member 10, it being only necessary to loosen the screw 18 and thereby free the head 18 thereof from binding engagement vith a blade 16 as it is slipped into or out of operative position. The loosening of said screw 18 also permits of the turning of a blade 16 to present the different raker teeth in proper working position. In Fig. 5, he blade 16 is formed with a tooth 16, which is flush with one side thereof, said tooth being adapted for raking in corners as well as between bricks.

In ointing, I may dispense with the raker blades 16 and use the member 11 for finishing narrow joints, the member 10 then serving as a handle. In finishing wider joints, the member 10 is employed as the smoothing element and the member 11 as the handle. For raking, the desired blade 16 is quickly and easily attached to the member 10 andreadily adjusted thereon to present the desired raker tooth 16 in working position. It is not necessary to remove the blade 16 from the member 10 when the tool is used for finishing, since the slot 17 permits of adjustment of said blade into position avoiding interference with the operation of said member 10.

Changes in the specific form of my invention, as herein disclosed, may be made Within the scope of What is claimed Wltlflout departing from the spirit of my invention.

Having described my invention, What I claim as new and desire to protect by Letters Patent is:

1. In a tool of the class described, a pair of tubular members of diii'erent diameters, each end of each member having a portion cut out longitudinally thereof and tapered, the cut out portions of the larger member being turned back to form connecting arms for the members, the smaller member being formed with slots to receive the free ends of said arms, each member comprising both a joint finishing element and a handle, one member serving as a jointer While the other serves as a handle and vice versa.

2. In a combination tool of the class described, a pair of connected members comprising finishers for joints and serving severally as grips in the handling of the tool, a raker blade having a plurality of raker teeth thereon and means for securing said blade to one of said members in position to permit of the application of a selected raker tooth and also in position avoiding interference with the operation of said member.

3. In a tool of the class described, a pair of finishing members, arms joining said members in laterally opposed relation, said members serving alternately as handles and jointers, a raker blade and means at one end of one of said members for clamping said blade thereon.

In testimony whereof, I have signed my name to this specification.

CHRISTIAN N. CHRISTENSEN.
